GALVAN IC BATTERY.

VSIPEGIFICA'IION forming part of Letters Patent No. 429,596, dated June 10, 1890.

Application filed January 3,1890. Serial No. 335,748. (No model.)

To all whom it may concern.-

Be it known that I, JOHN BEATTIE, Jr., a citizen of the United States, residing in Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Galvanic Bat-v A represents the outer jar, and B the por` ous cup standing on legs within the same. The bottom of this cup only is porous, the sides being glazed or otherwise stopped In the outer jar the copper is placed'in a solution of sulphate of copper, While the zinc and acid are placed in the porous cup.

C represents the zinc, which in. this instance is formedasa compact body`having a large liat` base. Its sides are coated with shellac, asphaltumJ` or other similar substance to prevent-chemical action, but the bottom is leftuncovered, and it is here, and here only, that action takes place. The Zinc is raised a slight distance from the bottom of the cup, and is'supported in that position by blocks of insulating material c', or the zinc may be suspended from above in any desired manner, and thus do away with the blocks c. The asphaltum coating of the zine is represented by C. This construction of cell necessitates that the chemical action shall take place in the lower-part,whe1e the solution is thus described my invention, I

treated to prevent chemical action, in combination'with a cup a portion of /whose walls only is porous, the remaining portion being non-porous,'or nearly so, the part-s belng located sothat the active portion of the zincl stands opposite or adjacent to the porous'portions of the cup, as set forth.

2. In a galvanic battery, a zinc element having'all of its surface except the bottom treated to prevent chemical action,in comblnation with a. cup whose bottom only is por- Y ous. l

3. In a galvanic battery, a zinc element having all of its surface except the bottom treated to prevent chemical action, in combination with a cup Whose bottom only is porous, the zinc being located inside the cup, but raised slightly off the bottom.

et. In a two-Huid battery-cell, an outer jar containing the copper and solution, a`cup located therein having nonfporous-sidesland a porous bottom, an acid'and zinc locatedn the cup, the zinc rendered active at its bottom only and being raised above the bottom of the porous cup, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses.
